13DESCRIPTION
14-----------
89d32d33
CC
15
16Given one or more existing commits, apply the change each one
17introduces, recording a new commit for each. This requires your
18working tree to be clean (no modifications from the HEAD commit).

20When it is not obvious how to apply a change, the following
21happens:
22
231. The current branch and `HEAD` pointer stay at the last commit
24 successfully made.
252. The `CHERRY_PICK_HEAD` ref is set to point at the commit that
26 introduced the change that is difficult to apply.
273. Paths in which the change applied cleanly are updated both
28 in the index file and in your working tree.
294. For conflicting paths, the index file records up to three
30 versions, as described in the "TRUE MERGE" section of
31 linkgit:git-merge[1]. The working tree files will include
32 a description of the conflict bracketed by the usual
33 conflict markers `<<<<<<<` and `>>>>>>>`.
345. No other modifications are made.
35
36See linkgit:git-merge[1] for some hints on resolving such
37conflicts.

45 Sets of commits can be passed but no traversal is done by

55 When recording the commit, append a line that says
56 "(cherry picked from commit ...)" to the original commit
57 message in order to indicate which commit this change was
58 cherry-picked from. This is done only for cherry

RW
59 picks without conflicts. Do not use this option if
60 you are cherry-picking from your private branch because
61 the information is useless to the recipient. If on the
abd6970a
JH
62 other hand you are cherry-picking between two publicly
63 visible branches (e.g. backporting a fix to a
64 maintenance branch for an older release from a
65 development branch), adding this information can be
66 useful.

69 It used to be that the command defaulted to do `-x`
70 described above, and `-r` was to disable it. Now the
71 default is not to do `-x` so this option is a no-op.

73-m parent-number::
74--mainline parent-number::
84989bd8 75 Usually you cannot cherry-pick a merge because you do not know which
7791ecbc
JH
76 side of the merge should be considered the mainline. This
77 option specifies the parent number (starting from 1) of
78 the mainline and allows cherry-pick to replay the change
79 relative to the specified parent.

83 Usually the command automatically creates a sequence of commits.
84 This flag applies the changes necessary to cherry-pick
85 each named commit to your working tree and the index,
86 without making any commit. In addition, when this
37a7744f
BD
87 option is used, your index does not have to match the
88 HEAD commit. The cherry-pick is done against the
8bd867ee 89 beginning state of your index.

91This is useful when cherry-picking more than one commits'
8bd867ee 92effect to your index in a row.

115git cherry-pick master::
116
117 Apply the change introduced by the commit at the tip of the
118 master branch and create a new commit with this change.
119
120git cherry-pick ..master::
121git cherry-pick ^HEAD master::
122
123 Apply the changes introduced by all commits that are ancestors
124 of master but not of HEAD to produce new commits.
125
be1b0558 126git cherry-pick master{tilde}4 master{tilde}2::
89d32d33
CC
127
128 Apply the changes introduced by the fifth and third last
129 commits pointed to by master and create 2 new commits with
130 these changes.
131
132git cherry-pick -n master~1 next::
133
134 Apply to the working tree and the index the changes introduced
135 by the second last commit pointed to by master and by the last
136 commit pointed to by next, but do not create any commit with
137 these changes.
138
139git cherry-pick --ff ..next::
140
141 If history is linear and HEAD is an ancestor of next, update
142 the working tree and advance the HEAD pointer to match next.
143 Otherwise, apply the changes introduced by those commits that
144 are in next but not HEAD to the current branch, creating a new
145 commit for each new change.

147git rev-list --reverse master \-- README | git cherry-pick -n --stdin::
148
149 Apply the changes introduced by all commits on the master
150 branch that touched README to the working tree and index,
151 so the result can be inspected and made into a single new
152 commit if suitable.

154The following sequence attempts to backport a patch, bails out because
155the code the patch applies to has changed too much, and then tries
156again, this time exercising more care about matching up context lines.
157
158------------
159$ git cherry-pick topic^ <1>
160$ git diff <2>
161$ git reset --merge ORIG_HEAD <3>
162$ git cherry-pick -Xpatience topic^ <4>
163------------
164<1> apply the change that would be shown by `git show topic^`.
165In this example, the patch does not apply cleanly, so
166information about the conflict is written to the index and
167working tree and no new commit results.
168<2> summarize changes to be reconciled
169<3> cancel the cherry-pick. In other words, return to the
170pre-cherry-pick state, preserving any local modifications you had in
171the working tree.
172<4> try to apply the change introduced by `topic^` again,
173spending extra time to avoid mistakes based on incorrectly matching
174context lines.
